Low headroom? Your sectional door options explained
If there is little space between the top of the opening and the ceiling, a low-headroom sectional door changes the track and spring layout so the door parks closer to the ceiling; some systems quote figures from about 70 to 125 mm. If even that will not fit, a side-sliding sectional door, which parks along a wall, needs almost no headroom.
Measure first
Measure from the underside of the lintel to the lowest point above it: ceiling, beam, pipe, joist or light fitting. Take readings at both sides and in the middle.
Option 1: low-headroom track
A low-headroom kit uses a tighter track path and may move the springs, so the top panel turns closer to the ceiling. From outside, the door looks the same. Expect a modest extra cost and a check on whether your chosen operator suits the kit.
Option 2: side-sliding sectional
A side-sliding door needs only a head track. It parks along one side wall, so that wall must be clear for roughly the width of the door.
Option 3: work on the opening
Sometimes lowering the door height slightly, by adding a timber or steel head detail, creates enough headroom. This is decided at survey and may involve building work.
